INTERCHANGEAIBLE BOAD 'IREA'IING MACHINE.

Application filed March 1, 1922. Serial No. 540,091.

an entirely practical, eflicient and relatively inexpensive machine especially adapted for the treating of soft clay and gravel roads.

Another object of the invention is to provide a machine of the character indicated interchangeably adapted .for; scarifying,

scraping, rolling and surfacing roads.

A specific object of the invention is to provide a machine of the character indicated employing a weighted roller, the position of which is shiftable or adjustable for the purpose of either varying the effective load or weight of the machine when itis performing certain functions or to act as a true leveling or smoothin roller.

Other objects of t e invention will more clearly appear from the description and claims hereinafter following. i

In the drawings forming a part of this specification, Figure 1 is a top plan view of a machine showing my improvements in connection therewith, certain parts being shown in section in order to more clearly illustrate details of construction. Figure 2 is a side elevation of the machine shown in Figure 1 and illustrating the arrangement of parts when the machine is adapted for either scarifying or scraping. In this figure the adjust-able weighted roller is shown in full lines in'a position trailing the rear wheels of the machine approximately at the road level. The dotted views of said roller indicate other positions which said roller may assume for the purposes hereinafter set forth. Fi Ire 3 is a view similar to Figure 2 but il ustrating the machine when employed for smoothing or rolling the road bed. Figure 4 is a detail sectional view corresponding substantially to the line 44 of Figure 2 to more clearly illustrate one of the scarifying prongs and method of securing the same in adjusted position.

tatably mounted on a -fixe A-nd Figure 5 is a detail sectional view corresponding substantially to the line 5-6 of Figure 1' illustrating more particularly the method of holding the rear weighted r ller in adjusted position.

11 said drawings, the machine is shown as comprising a frame des gnated generally by the reference character ;-a front rolli support B; rear wheels C-C; a weight dd rear-roller D; a scarifier E; a scraper F; a

gravel or other surfacing materialhopper.

r; and a liquid surfacing material tank H.

The frame A may be of any suitable substantial construction, the one shown in the drawings being formed of a plurality .of channels 10-10 arranged in a rectangular form and suitably united'atthe corners by gussets 11 11. Suitable cross braces and platform supports may be employed as indicated at-12-12 in Figure 1.

The rolling support provided for the machine at the front end thereof is preferably in the form of a wide tread roller indicated at B, the same being weighted and of a width corresponding substantially to the width of road bed to be treated. In actual practice, the roller B will preferably consist of an outside shell or tubular casing 13 anda concrete filling 14 with suitable anchors 15 for. the concrete, the anchors 15 being rigidly carried by the axle 16 which is extended thru the roller and suitably journaled, preferably in roller bearings, carried by the depending arms 17-17 securedto the frame. j

The rear wheels 0 are arranged as indicated, one on each side of the machine outside of the frame, the same bein preferably roaxle 18, ball bearings being also preferably employed. In this connection it will be noted that the rims of the wheels C are-concave in cross section, as indicated at 19 to thereby minimiz tendency of the machine to sideslip when on'a crowned road bed or when the scraper is being employed, which also has a tendency to shift the machine sideways.

The machine is adapted to be pulled, preferably by one or two horses or a tractor,

. thru a chain 20 attached to the machine for this purpose. When. horse drawn, it will be understood that the chain will have a whiflietree secured thereto, although the same is not shown in the drawing.

The scarifier E extends transversely of the machine and at right angles to the side members of the frame. As shown, the scarifier includes an angle iron 21 pivotally attached to the frame as indicated at 22 so as to adapt it to be swung from its operat1ve position shown in full lmes 1n l lgure 2 to its inoperative position, as shown by the full lines in Figure 3. The ad ustment of the scaritier is etl'ected by any suitable meansas for instance, the link 23 connected to the hand lever 24, which is pivoted to a suitable bracket 25 carried by the frame, said lever 24 having a hand grip and located so as to be convenient to the operator when the latter is sitting in the seat 26 supported on the frame. Suitable locking dog and stationary rack 27 and 28 may be employed in connection with the lever 24 to hold the scarifier in any adjusted inoperative position. In operative position, the upper flange 29 of the angle iron wlll bear against the under sides of the side members of the frame so as to prevent the scarifier from swinging counterclockwise as viewed in Figure 2. In addition to the angle iron 21, the scarifler includes a plurality of vertically extending fingers, or bars indicated at 30. The latter are preferably of isosceles triangle cross section as shown in Figure 4 and the same are adapted to be held in vertically adjusted position with respect to the angle iron 21, by any suitable means such as the U-shaped clamping bolt 31, nuts 32 and filler 33 interposed between said bolt 31 and the bar proper. Each of said bars is oppositely beveled at its ends as indicated at 3434 so that either end of the bar may be employed in scarifying the road bed. The bars 30 may be laterally spaced any suitable or desired distance.

The scraper F is of novel form and of inexpensive but substantial construction, the same as shown, consistin of a length of channel as best seen in igure 2 with the web of the channel extending vertically when the scraper is in normal operative position. The scraper F will extend angularly with respect to the side members of the frame A and in operative position, the upper flange 35 will bear against the under sides of the frame members so as to prevent the scraper from swinging counterclockwise as viewed in Figure 2. In order that the scraper may be moved to an inoperative position clear of the ground, the same is preferably pivotally supported from the frame of the machine as by brackets 36 36 mounted on studs 3737 carried by brackets 3838 rigidly secured to the side members of the frame A. In this connection, it will be noted that the pivotal axis of the scraper F extends parallel to the scraper as best shown in Figure 1. In order to adjust'the position of the scraper, any suitable mechanism may be employed to swing it in a clockwise direction as viewed ravages in Figure 2. Such mechanism may embody a .link 39 and lever 40 similar to the lever and link arrangement for positioning thescarifier E, the lever 40 being also located so as to be convenient of operation.

The weighted roller D, per Se, is preferably of the same type as the front roller B but of somewhat greater length and greater diameter so as to obtain greater weight. In both the rollers B and D, end plates 41 are preferably employed spot-welded Or otherwise permanently secured to the pipe casing or shell so as to prevent disintegrationand falling away of the concrete. Said roller D is rotatably mounted in bearings 42-42 formed at the outer ends of a pair of brackets 4343. The brackets 43 are in turn pivotally or circularly adjustably mounted on the stationary axle 18. In this connection, it will be noted that the brackets 43 are of suflicient length so as to permit the roller D to be swung around the wheelsC without engaging the latter. Each of said brackets 43, at its hub end, is provided with a rigid notched wheel 44 with which is adapted to cooperate a gravity influenced locking dog 45 pivotally mounted on a suitable portion of the frame, as indicated at 46. The notches 47 in the wheel 44 and the cooperating end of the dog 45 are such that, when they are in engagement, the wheel 44 and consequently the brackets 43 will be prevented from rotating in either direction. In actual practice, the weight of the roller D will referably be between 500 and 600 poun s and in order to adjust it, any suitable means may be provided but preferably, for simplicity and cheapness, the brackets 43 will be made of such cross section as to provide a plurality of arms 48-48 extending in different directions, said arms having openings therethru thru which to engage a rope or cable so that the horses or other tractive power may be utilized to lift the roller D to any desired position where it may be locked by means of the dogs 45 and wheels 44.

In order to obtain the greatest use of my improved machine, I may employ the tanks or receptacles G and H. The former is located well forward of the machine and is v adapted to contain gravel or other dry sur- F slightly lower than that of the scari er E so that both scarifying and scraping may be carried on simultaneousl By adjusting the roller D to the position indicated in Figure 3, it will be noted that the weight of the rear portion of the machine is taken off of the wheels C and is-sustained entirely by the roller D so that the latter isedapted to act as a true smoothing or levelin roller and with a maximum wei ht impose thereon. When the machine is being used for rolling ur oses, the scarifier and scraper will pre era ly be shifted to inoperative positions as indicated by the dotted lines in Fi re 3. Not only does the mechanismdescnbed permit of the adaptation of the machine for rolling, as above described, but it also facilitates the passage of the machine over railroad tracks and the like without danger of the scarifier or scraper becoming caught or broken. As clearly indicated in Figure 2, the roller D may assume other positlonsthan that of sustaining the weight of the rear portion of the machine and said other ositions of the roller D will depend upon t e effective weight desired on the machine to hold'it down in carrying out its scarifying or scraping operations. In the position of the roller D shown by full lines in Figure 2, the roller D travels on the top of the road bed without imposing any sub stantial weight on the machine. his is desirable under some conditions, as for instance when the machine is being employed to deposit surfacingmaterial on the road' bed. By lifting the roller D to the position indicated at D in Figure 2, a part of the weight of the roller D is imposed upon the frame but in such a osition as to detract somewhat from the e ective weight of the front roller B. In positions of the roller D, as indicated at D and D', the whole weight of the roller is carried by the frame, the po sition D producing a greater weighted effect on the forward flportion of the machine, thus serving more e ectively to maintain the scarifier and scraper in the dirt or gravel so as to perform their roper functions.

From the preceding description, considered in connection with the drawings, it will be seen that the machine which I have invented can be manufactured at com aratively small expense and yet will per orm the functions of several machines, which are of more expensive character, as heretofore commonly employed. Because of the simple arrangement of parts, my improved machine may be readily changed or converted from one use to another.

Although I have not shown the same on the drawing, it will be understood by those skilled in the art that I may attach a gutter plow on either side of the machine, thus further increasing the utility of the machine.

Although I have herein shown and descnbed what I no consider the preferred manner of carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
